Even if the dynamic parameters provided by ambient vibrations (AV) cannot be fully associated to the seismic response of buildings due to the scaling effect between weak and strong motion of structures, AV based methods have since gained more and more interest because of their low cost and fast operability. One crucial parameter is the value of the fundamental frequency which can be helpful for building health monitoring, damage assessment and modelling of the buildings. Most of AV surveys consist in installing accelerometers or velocimeters in the target building and recording ambient vibrations using digital and handheld acquisition system. It can also be worthwhile and safe to have the possibility to get the resonance frequency of buildings using remote system: worthwhile because of the repeatability of the measurements without entering in buildings, and safe in case of post-earthquake assessment of the building integrity when aftershocks are able to collapse the damage buildings. This paper demonstrates the ability of coherent LIDAR, a remote LASER system, to obtain the resonance frequency of the buildings. After a brief description of the target building, the two experimental approaches based on AV and LASER techniques are presented. Finally, a cross validation of AV and LASER methods is performed.
